National Fossil Day was established to promote the scientific and educational values of fossils. This nationwide celebration was first held on October 13, 2010, during Earth Science Week. The National Park Service and over 270 partners, including museums, institutions, organizations and other groups, joined together to celebrate fossils. Hundreds of activities were hosted across the United States allowing the public to better understand the world's fossil heritage. National Fossil Day 2011 was observed on October 12, 2011 with events at museums, parks, universities, and non-profit organizations. National Fossil Day 2012 was celebrated on October 17, 2012. The National Fossil Day Celebration on the National Mall in Washington, D.C. was the kick-off event. The 2013 National Fossil Day occurred on October 16, 2013. The 2015 National Fossil Day occurred on October 14, 2015 according to the National Park Service. Each year a new National Fossil Day logo is created depicting a prehistoric organism. The logos help to promote National Fossil Day and provide educational opportunities to share more information about fossils. The original National Fossil Day logo was created in 2010 and featured a fossil mammal known as the titanothere. In 2011, the marine reptile known as the mosasaur was used in the National Fossil Day logo. During 2012, the mammoth was used for the annual logo. For 2013, a Paleozoic invertebrate known as the eurypterid is featured in the annual logo. Each year a new National Fossil Day logo is created and is unveiled in mid-January on the event website: http://nature.nps.gov/geology/nationalfossilday/ The new logo will highlight another interesting story related to the fossil record of life. ==References== "National Fossil Day Events".
